Two Parameter Weibull Probability Plot

Tuesday, 21 February 2023, 10.10

Unweighted constrained simplex regression

Gradient:  1.0479        s.e. 0.0105
Intercept: -0.4092       s.e. 0.0832

Correlation Coefficient, r: 0.9699
Critical Value for r:       0.0501
Significance level used:    5.0%
Sum of squares:             310.8105

Best Estimates of the Parameters
sigma:  8.3156      'pseudo-linear' s.e. 0.0328
gamma:  2.7443      'pseudo-linear' s.e. 0.0312

The 'pseudo-linear' s.e.s are a lower limit to the s.e. and may significantly underestimate the s.e.
